The outer shoulder 21 is larger than the guide groove 11, and the threaded connecting portion 22 is smaller than the outer shoulder 21. It can be fitted into the guide groove to fit, and tighten the screw 23. Under the occlusal pull, the threaded connection part 22 can move in the guide groove 11, and the outer shoulder 21 can only move against the outer wall of the T-shaped flange 1.

The T-shaped flange 1 is provided with two screw holes 16 symmetrical to each other. A tightening screw 23 can be installed in the screw hole 16, and the tightening screw 23 is installed into the screw hole 16 for damping and clamping, by static friction. The tightening screw 23 can only be rotated when the tightening screw 23 is rotated under the action of the external force of the screwdriver. When the tightening screw 23 is not rotated, the tightening screw 23 is statically clamped in the screw hole 16. Alternatively, you can add viscous damping glue to the screw hole 16, so that the tightening screw 23 can be installed into the screw hole 16 to be stationary, and the rotation force of the tightening screw 23 is greater than the viscous force when the tightening screw 23 is rotated under the action of the external force of the screwdriver, which makes the tightening screw 23 to rotate.
